Definitions

  • the invention relates to a method for creating error entries of the participants of a data bus in a motor vehicle.
  • Typical subscribers of a data bus have the ability to detect errors of their own operation and / or errors of the output behavior, e.g. the transmission behavior, other participants of the data bus to recognize.
  • errors can be of different nature and nature, for example, temporary or permanent, safety-critical or non-safety-critical, service-relevant or not service-relevant.
  • servicerelevant in this context are errors on whose occurrence in the case of correct detection in a workshop typically a service action such as the replacement or repair of a device takes place.
  • Modern motor vehicles typically contain several dozen controllers.
  • the participant recognizing the error regardless of the type of error causes an error entry in a fault memory.
  • This error entry can be entered by the recognizing participant itself in a local error memory or it can be caused by the recognizing participants that another participant makes a corresponding error entry.
  • the hardware of a fault memory is unnecessarily burdened by the high number of write cycles associated with an unnecessarily high amount of fault entries. This may result in exceeding the number of write cycles provided for in the specification of the hardware of the fault memory and / or failure or malfunction of the hardware of the fault memory.
  • Modern diagnostic systems have the option of suppressing error entries depending on certain criteria, such as their safety relevance, in order, for example, to quickly and easily identify safety-critical errors.
  • certain criteria such as their safety relevance
  • certain errors are falsely hidden.
  • the service relevance of an error often can not be derived solely from the type of error. Rather, a determination of the service relevance often requires additional information, for example information on specific vehicle states at the time of the occurrence of the error or in the subsequent period. Masking according to criteria of the type of error can thus possibly lead to errors being overlooked for service-relevant errors.
  • DE. 10107367 A1 discloses a method for diagnosis by error pattern recognition with assignment of one or more error symptoms to a physical error, in which the error symptoms are arranged into an error pattern, the error patterns are logically linked to one or more matrices and the matrices contain information about the error patterns of known physical Errors included.
  • the method offers the possibility of repeated To avoid entries in an error memory as a result of recurring errors by detecting the associated error pattern.
  • a disadvantage of a method according to DE 10107367 A1 is that it is associated with a very high storage and computational effort.
  • errors of a previously stored in the error memory error pattern which may not be service-relevant, at least once entered in the error memory.
  • the object of the invention is to provide a simple method for creating error entries of the participants of a data bus in a motor vehicle, in which unnecessary error entries are avoided.
  • the object is achieved by a method in which is detected in recognizing a possibly servicerelevant error of the recognizing participants in an error state and outputs an error message to a second party, whereupon of the second participant depending on at least one predetermined condition, such as the determination of a State in which the detected error is dysfunctional, or the transition of the motor vehicle in such a state, a request for creating an error entry is issued to the recognizing participant and the recognizing participant in the case of receiving such a request, an error entry is made.
  • errors detected by one of the participants are first assigned to one of at least two classes, depending on their type of error. Depending on Error type or class is then immediately prompted an error entry or it will proceed as described above.
  • an error entry is promptly initiated by the recognizing subscriber.
  • the recognizing subscriber Upon detection of a fault of at least a second class, for example the class of non-safety-relevant and possibly service-relevant error, the recognizing subscriber is put into an error state and issued an error message to a second participant, whereupon the second participant depending on at least one condition Request for creating an error entry is issued to the recognizing participant and the recognizing participant in the case of receiving such a request, an error entry is made.
  • a fault of at least a second class for example the class of non-safety-relevant and possibly service-relevant error
  • An error entry to be made can be entered by the recognizing subscriber himself into a local error memory or it can be caused by the recognizing subscriber that another subscriber makes a corresponding error entry. Conceivable here is, for example, the cause of an error entry in a central error memory or the cause of an error entry in the error memory of a subscriber, which is closer to the error source in a hierarchical structure than the recognizing participants. Both the error detection and the making of error entries can be done cascaded.
  • a subscriber A who has detected an error, put himself in an error state and issue an error message to a subscriber B, the subscriber B has thus also recognized the error, puts himself in an error state and gives an error message to a subscriber C out, the subscriber C is after receiving the error message depending on at least one predetermined condition, a request to create an error entry to the subscriber B, the subscriber B depending on a predetermined condition, namely the receipt of the request of the subscriber C, a Request to create an error entry to the subscriber A, whereupon the subscriber A makes the error entry.
  • a method according to the invention is particularly suitable for application to a hierarchical structure of subscribers.
  • a higher-level participant typically decides whether a subordinate subscriber has to make or initiate an error entry.
  • a subscriber who has detected an error, sent an error message and put himself in an error state typically initially remains in this error state.
  • This error condition may be associated with limitations on the function of the subscriber and should not be maintained for an unnecessarily long time.
  • An efficient procedure for canceling the error state as soon as possible, but not too early, is now to cancel the error state after the expiry of a predetermined time constant in which the recognizing participant was in the error state but has not received a request for error storage , Likewise, it may be pertinent to trace the error condition cancel the occurrence of at least one predetermined event. In particular, in the absence of the error that led to the transition to the error state, such an event may be the detection of such an omission or that a request is received not to enter the error.
  • an error state of a recognizing participant is thus canceled after the expiry of a predetermined time constant without receiving a request for initiating an error entry and / or after the occurrence of at least one predetermined event, in particular the omission of the error.
  • the error state in order to avoid synchronization problems, it may be useful in a triggered by an event cancellation of the error state, the error state at the earliest after the expiry of a predetermined and from the omission, whose determination or another event to be measured time constant.
  • a further advantage of a method according to the invention is that the efficient control of the storage of fault entries can be used, as it were, for the efficient control of warnings to the driver of the motor vehicle.
  • warnings to the driver also apply, so that only safety-related and service-relevant faults should be displayed if possible.
  • the invention is accordingly when an error of a particular class, for. B. a safety-related error promptly prompted a warning.
  • an error of another class e.g. B. a non-safety-relevant and only possibly service-related error
  • a warning is issued only then and at the earliest when one of the participants issued a request or an occasion for an error entry.
  • such a warning is caused by the subscriber issuing the request to create an error entry quasi-simultaneously with the issuance of the request.
  • Fig. 1 shows schematically a data bus in a motor vehicle with several
  • Fig. 2 shows the communication flow in a method according to the invention with the participation of two participants.
  • a data bus 5 with several subscribers 1, 2, 3, 4, etc. in a motor vehicle is shown schematically in FIG.
  • FIG. 2 shows the communication sequence in a method according to the invention with the participation of two subscribers 1 and 2 of the data bus of FIG. 1. Subscriber 1 is subordinate subscriber 2 hierarchically due to the function.
  • a state transition 12 to a state 13a follows from the event that subscriber 1 detects an error.
  • the error is the absence of a message from another party's expected message.
  • participant 1 determines the class of such an error and the error is assigned to one of two classes.
  • Error class 1 includes safety-relevant and, in any case, service-relevant errors.
  • Error class 2 includes non-safety-related and only possibly service-relevant errors. Participant 1 assigns the error detected in the example to error class 2. This leads to state transition 14a to state 13b.
  • subscriber 1 sends an error message to the functionally hierarchically superior one
  • the error message contains various information about the detected error, e.g. B. the error type "missing message of a
  • Subscriber 1 also goes into an error state by setting a corresponding data bit.
  • a request to create an error entry to the recognizing participant should only be issued if a function in which the participant 1 is involved is marked as activatable on the basis of a vehicle state, in this case the driving speed, and the driver of the motor vehicle Within a given time constant, here 60 seconds, try this Activate function. Otherwise, a request should be issued to the recognizing participant to cancel the error state again.
  • a timer is started at the transition to the state 15a.
  • the state transition 16a after a period of time which is less than the predetermined time constant, is triggered by an attempt by the driver of the motor vehicle to activate a function in which the subscriber 1 is involved and which is identified as activatable based on the driving speed.
  • subscriber 2 sends a request to create an error entry to the subscriber 1 and causes the issuing of a warning to the driver of the motor vehicle.
  • participant 1 had assigned the detected error in state 13 of error class 1, an immediate state transition 18 to state 17 and the immediate initiation of a warning to the driver of the motor vehicle would have been the consequence. This would have been the case, for example, with an error of type "defective component X". If the time constant in state 15a lapses, without an attempt by the driver of the motor vehicle to activate a function in which the subscriber 1 is involved and which is identified as activatable on the basis of the driving speed, the state transition 19 is thereby initiated. The error state of the subscriber 1 is canceled again, the fault memory of the subscriber 1 remains empty. The participant 1 is thus again in the initial state 11.
  • the one received by the subscriber 1 from the subscriber 2 is the one received by the subscriber 1 from the subscriber 2
  • Participant 3 passed. This is particularly useful if it is known to the participant 1 that participant 3 represents the source of error or at least in a hierarchy of participants closer to the
  • Error source is located as participant 1.
  • the request received by the subscriber 1 from the subscriber 2 for making an error entry is forwarded by the subscriber 1 to a subscriber 3 equipped with a central fault memory.
  • Subscriber 4 informs the subordinate subscribers which fault conditions are to be maintained or canceled.
  • An extension of the invention sent error messages and prompts for additional content such as error parameters, information on possibly and / or factually functionally impaired by the error participants and action instructions are also contemplated and are within the scope of the invention.
  • the application of a method according to the invention means that only safety-relevant and / or service-relevant errors are entered into a fault memory. This makes troubleshooting in a workshop much easier and faster.
